Terms of Use

Updated on 12 November 2026

The app

Use of the app is covered by Apple's standard license for App Store apps, the Licensed Application End User License Agreement. What follows covers only the account and sync, which Apple's license does not.

The account and sync

The account is optional: Charcal works without one. If you create it, our server keeps a copy of your data to bring it to your devices. What it stores is listed in the privacy policy.

Keep your password, your personal token and your calendar address to yourself: anyone who has them can read your tasks.

AI assistants and other tools

If you connect an AI assistant, the command line or another tool with your personal token, it acts on your behalf: what it reads, adds, changes or deletes in your account counts as done by you. Connect only tools you trust, and regenerate the token if you stop using one.

Your content

What you write in Charcal stays yours. You only give us permission to store and transmit it as far as needed to sync it across your devices. We do not use it for anything else.

Fair use

Use the service for your own personal or work planning. You may not:

• try to get into other people's accounts;
• overload the server or work around its limits;
• use the service to store or distribute illegal content.

We may suspend or close an account used for abuse. Where possible we will warn you first.

How the service is provided

We do our best to keep sync working at all times, but the service is provided as is, with no guarantee of continuous availability. Your tasks stay on your device in any case, and the app works without a connection.

To the extent the law allows, we are not liable for indirect damage arising from the use of the service or from the service not working.

If we ever decide to stop the sync service, we will tell you in the app or by email at least 30 days before. Your tasks stay on your device, and until the end you can ask us for a copy of what is on the server.

Closing your account

You can delete your account whenever you like in Settings, Account, Delete account. Your data is deleted from the server right away; technical logs and backups expire on their own within a week, as the privacy policy explains.

If these terms change

We update the date at the top of this page whenever these terms change. If something important changes, we will also tell you in the app or by email before it applies. If you do not agree, you can delete your account at any time.

Governing law and courts

Swiss law applies to these terms. The courts of Lugano, Switzerland, have jurisdiction. The rights your own country's law gives you as a consumer remain in force, including the right to go to the courts where you live.
